To answer your original question about "public measurements", besides the two companies you already know about, the only other I know of that does that is Salk.
Toole and Olive’s philosophy at Harman is that people prefer flat FR, so between their designs and DBT process, Revels usually measure very flat. As do PSB. Many studio monitors (i.e. Mackie HR) measure very flat. Technics’ new bookshelves measure fairly flat up to 7kHz and their off-axis graph is very good (Stereophile - Class A 2016). Only handle 50 watts though.
Stereophile and SoundStageNetwork show the FR graphs of many of the speakers recommended above as being all over the place. On- and off-axis smoothness is one of the key features I look for in cone speakers. But then again, some people prefer a colored sound. However, my philosophy is that if you start from flat you can more easily tweak the EQ to suit your needs.
